' Be it known that I, (immen- Frame citizen of the United States, resid ng at St. Louis, Missouriyhave invented a certain new and useful Improvement" in Electric-Motor Trucks, of which the followin'g'is a full, and e'xactdescription, such as will en-- others 'jskilled' in the art to' which it ence being ings 'forming part of 'thisspecification, in which-Y v v plan view of an electric momy mproved construction. -Fig. 2is a side elevation of: the truck, with parts in vertical section.

upon elliptic springs 5, which lattr are car-1'." F ried upon a spring plank suitable pedestals 10, which latter are rigidly fixed.

pieces of the truck frani .70 4 of pedestals and interposed between'these g' equalizer bars and the wheel :pieces'of thefj are usual compression),

In order to materially strengthen the side frames of the truck and particularly the;

lower portions thereof equalizer .bars 12 are arranged beneath the wheel pieces of thei portions12 of said go vertically disposed slots. Y 1.0 formed in the lower portions'of the" pedestals 10. Fixed on these end ortions"* 12 and bearing against the outer aces pedestals 10 to the:

erein arebrackets The'journal boxes 9'are provided with depending brackets 9 which straddle the' of the bar between the edand passing through these brad ets Diagonally disposed braces 13 are" fixed at their upperends to the wheel pieces. 1,?

space between the pedestals, and these divided lower portions are fixed to the lower portions of the pedestals 10'- on the"outer'"" faces thereof. Interposed between the bars'jioo 12 and; the wheel pieces 1'"adja.ce nt'to the g in11er= pedestals' are the usual compression Springs. i The'con'struction just described permits the Wheel pieces tO IIIOTE' \erticlly' with re'-' spect to the journalbcxes 9 and the equalizer bars 12, and during such vertical movement the end portions 12 0f the equalizer bars move through'the vertically disposed slots in the lower portions of the pedestals. The brackets 12? carried by the end portions of. the equalizer bars prevent said ars from moving lengthwise or horizontally with respect to the pedestals. The braces 13, in connection with the equalizer bar 12, form practically a continuous bottom 'tie for the pedestals and wheel 0 pi'eces, and which continuous tie performs the function of a' tension member, thus 'materially increasing the strength and rigidity of the side frames.

The brackets used for yieldingly supporting and connecting the motor frames with .the end rails 2 each comprise a vertically disposed body portion l4,the ends of which are bent at right angles relative to the bodyportion, ,as designated by 15, and these'end o portions occupy positions immediatelykaboveg land below the end rail 2. The body portions 14 ofth'es'e brackets are detac ably fixed in any. suitable manner to'--lugs\ 16 formed integral with the side portions} of the motor frame 11. Suitableaperture tare formed in the end portions of the bent eufds ,15 of eachbracket, and corresponding apertures are formed; through the end rail, 2. i Bolts 17 are insertedthrough the, co 'e o sp'onding aperturesin theends 15, and rail '2, and compression springsl8 are located upon the bolts LZ, and interposed between the rail 2 and the bent ends. 15 of the bracket. A nut.or key 19.is -located upoa 5 the-lower end of each bolt 17 for the pm-5 pose of holding the same in place. This icon; I struction forms a direct connectiorr betweenl the. motbrfframe and the end rail oflthdfi} truck and the motor frame is yieldingly'v 40 held, with respect. to the motor frame,* by' the springs 18 interposed between the rail.

2 and the ends of the bracket 15.

' The springs 18, between the ends of the bracket and the end rail, perform the function of shock absorbers for the motor frame,

and thus the greater portion of the shocks and jars, which might betransmitted frem the axles and motorframe to thetruck frame and vice versa, are eliminated.

The bolts 17 are inserted from the top through the openings in the brackets and end rail 2 so thatin ease of the loss of the nut or key from the lower end of the bolt, the latter will retain its position, and, cruise 6 qucntly, hold the parts in their working positions.

While I have shown and described the yielding support for thefmotor frame as applied to outside hung motors'it will be readily understood that the same construction,' namely a bracketand spring, can he advantageously employed on inside hung, motors, and in the latter case the bracket and spring are connected to one of the inncr cross members or transoms of the truck.

Thus it will be seen how I have constructed a truck having side frames of great strength. and rigidity, and the motor frames -of which truck are yieldingly connected to and supported bythetruck frame. It will be readily'understood that minor changes in the construction and arrangement of parts can be made in my improved electric motor truck without departing fromthe spirit of my invention, the scope of which is set forth in the appended claims. I claim, I 1. In an electric motor truck, a truck frame having wheel pieces, pedestals depending therefrom, a vertically movable equalizer bar betwe' n the lower ends of the pedestals and diagonally disposed bars fixed at their upper ends to the wheel pieces and I the lower ends of which braces are divided andfixed to the lowb r ends of the pedestals on the outer faces thereof. i I 2. In an eleetric motor truck, atrnck side v \framecomprising a tvheel iece, pairs of \pedestals fixed to anddepen ing therefrom, journal boxes between'e pairs of pedestals, an equalizer bar conn'cted to the journal boxe's, and diagonally disposed brace {membersfixed to the end pdrtions of the wheel piece at their upper enpds, the lower ends of which brace members tween the pedestals below the journal boxes, and-\said brace members ing fixed to said pedestals. w

3. In an electric mo r truck, a truck frame having wheel pie es, pedestals .aro ranged inpairs, which p destals are fixed toand depend fro' the w eel pieces, a vertically movable equalizer ar arranged between the lower ends of th pairs of pedestals a d diagonally dispose braces fixed to- 5 the erid portions of the wheel pieces at their upper (ends, their lower ends being divided and fix'edgto the lower portidns of the pedes tals on \the outer faces there if, which equalizer hairs, and diagonally iform the lower chords of th side frames'of the truck.' v

4. In anelectric motor t'ruc thegcombina- ;tion with a truck frame havi g wheel pleees, pedestals depending ther'fro and. journal boxes betwecn'the pedestals, f a continuous =lowcr chorjd for the truck sid frame, which equalizer l ar connected to :the journal boxes, .and diagonally disposed b' a members, ex- ;-tending downward from ,theend portions of the wheel pieces, the lower nds of which f brace members are divided and are fixed to the inner and outer side faces of the pedes-- tals below the journal boxes. l

5. In. an electric motor triuek, a motor frame support eom;--' -in,4' a bracket fixed to the motor frame, the ends of which'bracket extend above and below a transverse member of the truck frame, and lsprings interspan the space beisposed braces 1 lower chorjd comprises avert cally movable bracket and the transverse member of the truck frame. y

. 6. In an electric motor truck, the combination with a motor frame and truck frame, of a bracket positioned on the motor frame, parts of which bracket occupy positions above and below a part of the truck frame, compression springs interposed between the ends of the bracket and the ad .jacent part of th'e'truck frame and means passing through the bracket, compression springs and the corresponding portion of the truck frame for holding said springs in operative! position.

7. In an electric motor truck, the combination with a transversely disposed part of the truck frame, of arms rojecting from the motor frame above and elow the transverse part of the truck frame, compression springs interposed between said arms and the transverse portion of the truck frame and a bolt passing through said arms,

through the springs and through the transverse portion of the truck frame.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses this 6th day of September, 1911.
